Preparedness/Response Goals
• Detect, control, and contain the FAD in animals as quickly as possible • Eradicate the FAD using
strategies that seek to stabilize animal agriculture, the food supply, the economy, and protect public health
• Provide science- and risk-based approaches and systems to facilitate market continuity for non-infected animals and non-contaminated animal products
SES: Introduction
• The SES Plan promotes food security and animal health through continuity of market
planning during a HPAI outbreak
• This plan makes specific science- and risk- based recommendations
• Emergency decision makers (such as IC) should use THIS TOOL
• Ultimately this is a TOOL that is essential to use before and during outbreaks
SES: Who?
Collaborative Team: • Multiple Private Industry
Members
• USDA – APHIS - VS • USDA – CEAH
• University of Minnesota • Iowa State University • State Departments of Ag and
Health
• United Egg Producers • United Egg Association • American Egg Board
SES: Development
• Based on current research and practice in: – Virology
– Flock husbandry – Epidemiology – Risk-assessment
• Uses science- and risk-based preparedness and response components
– Provide guidance on permitting the movement of egg products from a Control Area
• Plan provides a high degree of confidence that egg industry products that are moved into market channels do not contain HPAI virus
SES: How?
SES: How?
• Definition of Risk Assessment
– Risk assessment is a scientifically based process to qualitatively or quantitatively characterize the likelihood of exposure to a hazard and the resulting adverse consequences
• Objectives of SES Risk Assessments
– Disease and commodity specific – Proactively done
– Science and risk base approach
– Provide confidence for decision makers on permitting the movement of the commodity
SES: Risk Assessments
SES: Risk Assessments
• Risk Assessments Include:
– Current every day industry practices – things already done!
• Standard Operating Procedures (SOP) • Regulations – FDA, FSIS, APHIS • Good Manufacturing Practices
– In an Outbreak - Proposed Additional Mitigations • Elevated Biosecurity
• Surveillance Strategy
• Cleaning and Disinfection (C & D) Guidelines – Evaluated using accepted scientific techniques
SES: Risk Assessments
Risk Assessment Uses:
– Risk Categories • Negligible Risk: Insignificant • Low Risk: Unlikely – Risk Assessors
• Evaluate level of risk and whether or not a hazard will occur in a scenario
– Industry/Regulators – use risk
assessment results
• Regulators ultimately decide what is an “acceptable level of risk” for their area and incident
SES: Voluntary Preparedness
Component
• Part of the Secure Egg Supply (SES) Plan
– Available on a VOLUNTARY basis to egg producers – Reduces the time required to meet the criteria for
moving whole shell eggs.
• Objectives of the Voluntary Preparedness
Component
– To minimize the risk of exposure of poultry flocks to HPAI and to thereby limit the spread of HPAI during an outbreak
– To provide a high level of confidence that whole shell eggs entering market channels for human
consumption are free of HPAI virus.
• Voluntary Preparedness Component includes: – Enrollment in the program BEFORE an outbreak – Audits for minimum biosecurity standards – Location verification of participating farms – Epidemiology data
• Identify potential exposure during an outbreak • To document flock production parameters
– Active surveillance in each layer house – A secure website to share information with
Incident Commanders and authorized personnel
SES: Voluntary Preparedness
Component
SES: How?
SES: Permit Guidance
• Permit Guidance Development
– Risk assessments, surveillance guidelines, truck and driver biosecurity and product specific biosecurity measures
– Science-based guidelines for permitting the movement of eggs and egg industry products from operations in a HPAI control area • Permit Issued for Movement
– If flocks inside the control area meets permit requirements
SES: Permit Guidance
Permit Guidance – Pasteurized Liquid Eggs
SES: Epi-Questionnaire
• Epidemiology Questionnaire Includes: – Traceability information • Premises ID • GPS coordinates – Production parameters are normal • No clinical signs • No abnormal mortalitySES: How?
SES: Surveillance
Requirements
• Mortality and Production Parameters – Daily flock monitoring – signs of HPAI – Normal daily mortality
• An increase in mortality is defined as daily mortality greater than 3 times the past 7-day average and greater than 0.03%
• If mortality elevated other diagnostics needed
– Monitor with RRT-PCR Testing
• For those flocks not displaying mortality increase
SES: Surveillance
Requirements
Testing Criteria: • RRT-PCR testing on: – 5 or 11-bird poolsamples per 50 dead – Must be dead or
euthanized SICK birds – Must be done on each
house on the premise • Negative Tests
– Negative tests are required daily for product that moves daily
SES: Surveillance
Requirements
Sampling:
• Performed by:
– State or Federal regulatory officials – Individual authorized by Incident Commander • Procedure:
– 5 or 11 oropharyngeal swabs from 5 or 11 dead birds per house
– Swabs are pooled
– Samples submitted to authorized state veterinary diagnostic laboratory on same day of collection
– Laboratory transmits RRT-PRC test results to Incident Command
– Incident Command reports results to farm manager • Test Not Negative:
– Additional diagnostics will be conducted
– If daily mortality spikes over normal production parameters additional diagnostics will be conducted
SES: C & D and Biosecurity
Cleaning and Disinfection (C&D) Biosecurity
• Truck and driver biosecurity • Product specific biosecurity • Premises Biosecurity • Cleaning and disinfecting guidelines • Permitted movement checklists
SES: How?
SES: Example Permit
Egg Movement with SES Plan
Shipping
Layer Flocks
Permit
SES: Incident Command
• SES Plan provides the IC with: – Proactive risk assessments
– Surveillance and epidemiological data – Suggestions for truck and driver and
product specific biosecurity – Permit guidance
• IC makes final decision on
permit for product movement
SES: Risk Assessment
Commodities
• Commodities :
– Pasteurized Liquid Egg – Non-Pasteurized Liquid Egg
– Washed and Sanitized Shell Eggs (to Premise without Poultry)
– Washed and Sanitized Shell Eggs (to Premise with Poultry)
– Nest Run Eggs – Shells and Inedible Egg – Hatching Eggs – Day-Old Chicks
SES: Implementation
• Who uses the SES Plan?
– Incident Commanders – government officials that will lead a response plan in case of an outbreak
– Poultry Managers
• How do they use the plan? – First know it exists!
– Summary of Permit Requirements is the most comprehensive and fastest source
Secure Egg Supply: Benefits
• Departments of Agriculture • State Departments of Health • USDA – APHIS • USDA – CEAH • Private Industry • American Egg Board • United Egg Producers • United Egg AssociaCon • University of Minnesota • Iowa State University

Government
Secure Egg Supply: Benefits
•
Public/private partnerships are the only
means for true success
•
Deeper understanding of:
•
How industry works
•
Government’s roles and
responsibili;es
•
This collabora;ve effort is a model for
addressing issues in other industries (i.e.
FMD)
